Montana has a varied climate and terrain that greatly affects its flow conditions. The state boasts of major rivers such as the Missouri, Yellowstone, and the Clark Fork, which drain into the Mississippi, Missouri, and Columbia Rivers, respectively. Montana also has a number of reservoirs/dams, such as the Fort Peck Dam and the Hungry Horse Dam, which serve as major power sources and water storage for the state. The state's hydrology is influenced by its mountainous terrain, which leads to high precipitation levels and generates snowpacks. These snowpacks, in turn, largely determine the state's flow conditions in the summer months. Montana's flow conditions are also affected by its climate, which is characterized by dry summers and cold winters. Overall, Montana's flow conditions are shaped by a mix of climatic and topographic factors, including watershed, snowpack, and precipitation.
